I  am trying to implement digital filter  for power factor correction (PFC)  for onboard charger. A filter needs to be implemented in the code  after sampling  ADC  samples for  AC input voltage and current.  Which software tool  (open source ) I  should use , what design steps i should take to design digital filter. I am using XMC1302-T038x0200 development board for PFC.

Hi Rakesh,

If you are looking for digital filter implementations, you can check out 

https://www.infineon.com/cms/en/product/promopages/aim-mc/dave_downloads.html

The examples like BUCK_PCC_DIGITAL_POWER_EXPLORER_XMC13 which uses peak current control mode. You may refer that for your exact application.

Best Regards,

Hi,

 

   Thank you for posting on the Infineon Community. 

I see that you are using XMC uC for designing your PFC circuit. 

 

I suggest you to go through the following Application note from the evaluation board EVAL_3KW_DB_PFC_C7,

https://www.infineon.com/dgdl/Infineon-EVAL_3KW_DB_PFC_C7-AN-v01_00-EN.pdf?fileId=5546d4625e37f35a01...

 

This AN has detailed explanation on how to carry out your requirement.
